COLUMN-GUIDE FOR CAB-TRUCKS.

To all whom it may concern:

Be it known that I, CHARLES F. MURRAY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Column-Guides for Car- Trucks, of which the following is a specification.

My invention relates to improvements in railway car-trucks, and ertains more par- 'ticularly to the 'means 'oiusupporting. the bolster and retaining it in place so that it may be readily and quickly removed from 'the truck and side-frames.

Ordinarily, heretofore, the bolster has been removed from the truck by drawing it lengthwise through the central bolster and spring opening in one of the cast-metal side-frames. Owing, however, to the great depth of the bolsters at their middle portions as they are frequently constructed at present it is diffi- ."cult and" sometimes impossible to withdraw the looslter in this manner, the hole or aperture in the side-frame having an insuflicient vertical dimension to allow the withdrawal of the bolster in the manner indicated. In most truck constructions the bolster is long enough to extend through the aperture of the side-frames and have guiding lugs or ribs coactin with the side-frames to prevent or limit on itudinal shifting of the bolster.

One object of my invention is to modify the usual construction so that. even though the bolster is of great depth at its central part it can nevertheless be pushed outwardly through the aperture of one of the side frames to release its other end from the opposite side-frame, whereupon its freed end may be movedout of the truck and shifted 4O lengthwise in the opposite direction to withdrawits other end from the side-frame through which it had previouslybeen temporarily projected, and thus free entirely from the truck. 15 In my improved construction the bolster has no column guides, its ends resting o destings forming combined spring caps a id column guides. In the preferred embpi imcnts of my inyention tongue and groove connections between the bolster and Castings restrict/or limit lengthwise or -longitudinal shifting of the bolster. This tongue and g toove are located either at the bottom ofthe bolster or on one or more sidesof the same,

On the accompanying drawings, forming part of this specification, I have illustrated several desirable embodimentsof my inven-- tion, and throughout the various views like reference characters refer to the same parts.

On these drawings Figure 1 is aside elevation of a portion of a car-truck embodying my invention; Fig. 2 is a central vertical section through the upper portion of the sideframe, column guide casting, and bolster shown in Fig. 1; Fig. 3 is a section on line 3 3of Fig. 2-; Fig. 4 is a fragmentary side elevation of the construction shown in Fig. 2; Fig. 5 is a-horizontal section on line 55 of Fig. 4, the bolster being omitted; Fig. is a perspective View of the combined cci "an guide and spring cap; Fig. 7 is a side cleats tion of a=portion of the car-truck illustrating a modification of the construction shown in Fig. 1; Fig. 8 is a perspective view of the end portion of the bolster used in the truck shown in Fig. 7 Fig. 9 is aperspective view of the column guide casting employed in the truck shown in Fig. 7Fig. 10 is a central vertical cross-section throu h the the truck, the bol ster being unsectioned; Fig. 11 is a horizontal section on line-1111 of Fig. 7, the bolster being omitted; Fig. 12 is a horizontal section on line 12-12 of Fig. 10, the bolster being omitted; Fig. 13 is a sid. elevation of a part of the car-truck embeding another modification; Fig. H is a pcrsp iive view of an end of the bolster used in this truck: 15 is a perspective view of the column guide casting used in this truck; Fig. 16 is'a vertical cross-section through the top portion of the side-frame, the column guide casting and bolster being unsectioned; ,Fig. 17 is a horizontal section on line 1717 of Fig. 13 and Fig. 18 is a horizontal section on line 18-18 of Fig. 16, the bolster being omitted.

Referring first to the improved structure illustrated in Figs. 1 to 6, inclusive, it will be noticed that the car-truck has a cast-metal upper portion of side-frame 30, a central opening being provided in the side-frame for the accommodation of the springs and bolster, and in this particular embodiment of my invention this opening 31 is enlarged at its lower portion at 32 for a purpose hereinafter indicated. The

car-truck has a spring seat 33 shown in Fig.

1, on whichare superposed a plurality of coil compression springs 34, on the top ends of which is seated a casting 35 formin a combined column ide and springcap. his casting, as is clear y indicated in the figures, has a bottom wall 36 e nipped on its bottom surface with a downward y-extended curved flange 37 to retain the springs in position. Upstanding from the opposite ends of the floor or wall 35 :is the air of vertical parallel end walls 38 sition, as indicated in the figures, into the en larged portion of the centralopening. Across the top face of the bottom wall 36 and joining the end walls 38 is an upstanding rib or Web 41 which is adapted to fit in a transverse groove 42 on the under surface of the bolster 43. It will be noticed that the bolster 43 is shorter than usual, and is merely long enough to hook over the rib 41 of the casting, as is clearly indicated in Fig. 2. v

To remove the bolster, the springs 34 are taken out, the casting 3-5 dropped and withdrawn laterally through the openings 32 of the pair of side-frames, and then the bolster may be withdrawn longitudinally through the central 0 ening of one of the side-frames, provided it is not of too great depth at its central portion. If this latter condition is resent, however, the bolster can nevertheess be readily removed after the castings have been taken out, by ushing the same outwardly through one of t e openings of one side-frame until the other end of the bolster is freed from the opposite side-frame, whereupon this freed end may be lifted out of the truck, the whole bolster being then readily removed. It need hardly be mentioned that the cooperating ribs 41 and grooves 42 of the castings and bolster maintain the latter in proper position and prevent its longitudinal displacement under normal conditions.

n Figs] to 12, inclusive, another form of the invention 1s set forth, the chief'difi'erence between this truck and that of Fi s. 1-6 being thatthe central opening44 o the sidethe central opening 44, or

frame 45 is not enlarged at its lower portion, but has its two vertical edges parallel, as indicated. The bolster 46 is much like the bolster 42, its distin uishing characteristic being the transverse s 0t 47 on its under surface, which, instead of being rounded as in the previous instance, is substantially rectangular in cross-section, as is also the rib 43 of the casting 49 which it receives and with which it cooperates to limit and restrict lengthwise shifting of the bolster. The side walls 50 of the casting .49 are not tapered, and each has on its outer face a single guiding rib-51 which is adapted to cooperate with either the outer or inner surface of the sideframe, according to the manner in which it is. inserted in the frame. To remove the bolster, it is merely necessary to lower the casting 49 sufficiently to free the rib' 48 from the bolster, whereupon the casting may be taken out from that side of the side-frame against which the guiding ribs 51 have been coacting. The bolster may then be withdrawn through in the manner described above.

Although I have shown the casting 4?, with may be removed the ribs 50 cooperating with the outer face of the side frame, it will be perfectly apparent I that the casting may be reverse and have the'ribs coact with the inner face of the frame.

In the modification shown in Figs. 13 to 18 the side-frame '45 has a straight opening 44 and the column guide casting 52 is much like that illustrated in Fig; 6', except that instead of the single horizontal rib.41 the casting has on the inner faces of its upstanding end walls 53 the air of guides 54 ada ted to fit in the verticai side slots 55 of the liolster 56. The outer face of each of the walls 53 has a single guiding rib 57 which may abut against either the outer or inner face of the side-frame, ac-

cording to how the casting is side-frame.

To remove the bolster from this truck it necessary to take out the springs and drop the castings 52 sufficiently so as to free the guides 54 from the slots 55, after which the castings may be taken out sidewise from the side-frame, since the ribs 57 are present only on one side of the frame.

Although I have described in detail the placed in the precise and'exact structural features of the various forms of devices illustrated, it is to be understood that my invention is not lim ited strictly to these features, since they may be modified considerably without departing from the spirit and substance of my invention.
